Environment is: Oracle 817 on IBM RS/6000 AIX 433
I have 4GB RAM on the box and Page/Swap is about the same.
Presently I am using close to 1GB of RAM towards 5 instances of ORACLE production environments.
How can I know, how much of memory/RAM is used for :
Oracle Processes , I mean connections.. (SGA, I know)
Batch Jobs
Unix Processes etc.,
Running 'top' in the terminal should help you look at which processes are taking up the most memory/CPU... If you need to go further than that, I'm sure there are other utilities but I can't name them off the top of my head.
